Start: Position a Swiss ball alongside a pulley machine. Lower the pulley to the floor. With your back on the Swiss ball and your knees bent at a 90-degree angle, hold onto the handle with both hands and straight arms. Position your hands toward the pulley, and keep your eyes on them.

Movement: Keeping your arms straight and your eyes on your hands, pull the handle straight across your body until it’s directly above your head. Return to the start under control and repeat. Do all your reps for one side and then switch sides.
